Arm slings



Sept. 24, 1957 P. sTRlND'EN ARM sLIN'cs Filed Aug. 18, 1955 United States Patent O ARM SLINGS Peder Strinden, San Francisco, Calif. Application August 18, 1955, Serial No. 529,144 i 1 claim. (C1. 128-94) This inventon relates to improvements in surgical appliances and has particular reference to an arm sling adapted to be suspended from the shoulder of a person for comfortably supporting an injured arm in a position substantially at right angles to the Vertical Suspension portion of the appliance.

The principal object of the inventon is the provision of means for readily adjusting the shoulder engaging portion of the device relative to an arm supporting frame to thus permit the lowering or raising of the frame relative to the shoulder engaging portion.

An additional object of the inventon is the provision of means permitting pivotal movement of the 'frame relative to the shoulder engaging portion.

A further object of the inventon is the production of a device of the Character described that is simple in construction, economical to manufacture, light in weight, yet strong and durable, easily adjustable and highly efiicient and serviceable in use.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and wherein for the purpose of illustration like numerals designate like parts throughout the same,

Fig. l is a front elevatonal view of the appliance shown in an operative position,

Fig. 2 is a side elevational view of the same,

Fig. 3 is an enlarged detail view partly in section and partly in elevation disclosing means for connecting the extension and the tubular body of the inventon, and

Fig. 4 is a similar view and likewise disclosing an auxiliary fastenng means that is employed.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodment of my inventon, the numeral 6 designates, as a whole, a frame for slidably retainng therein the forearm of an injured arm A. This frame is preferably made of rigid spring wire and is of a substantially U-shaped configuration. A rear split horizontal rod of the frame is ndicated by the numeral 7 and continues downwardly to form side portions 8 thatv are then turned upwardly as at 9 and continue into a front horizontal bar 10 that lies n a plane below the plane of the bar 7 and is substantially spaced therefrom to define a cradle or sling that serves to support the forearm of the user.

The means for suspending the arm carrying frame from the shoulder of a person comprises a hook-shaped extremity 11 that is adapted to be draped over the shoulder. This hook element or extremity is preferably flat and is equipped at its lower end with a rounded buttonshaped element 12 that assures comfort to the wearer and eliminates a snagging of the clothes when the appliance is in use.

Integrally formed with the hook element and depending therefrom is a tubular member 13 having a lower open end 14. It will be noted that said member is provided with a plurality of spaced openings 15 that are adapted to receive a looking screw 16. A sleeve 17 encompasses the split rod 7 and passes through the lower end of a solid Vertical bar 18. The upper end of the bar enters the open end of the tubular member and the screw 16 serves to secure the bar and member 13 in a predetermined adjusted position. Accordingly, the device can be vertically raised or lowered to the desired height. The screw 16 serves to detachably secure the member 13 and the bar together.

A lower screw 19 provides an additional means for securing the frame to the bar 18.

By virtue of the construction recited it will be obvious that the frame and tubular body can be readily adjusted relative to each other and further that the said frame can be tilted as desired.

It is to be understood that the form of my inventon herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the shape, size, material andearrangement of parts may be resorted to without departing from the spirit of the inventon or the scope of the subjoined claim.

Having thus described my inventon, I claim:

An arm sling embodying in its construction a flat curved resilient portion adapted to be positioned on the shoulder of the user, a protective button provided on the free end of said portion, a tubular member having spaced openings therein and integrally formed with said flat portion and a frame for supporting the forearm of the user, means connecting said frame to said tubular member and comprising a Vertical bar pivotally secured at one end to said frame, and a fastening element for detachably securing said bar to said tubular element, whereby the bar is adjustable relative to said tubular element.
